Note that if Ted had lived in the UK like Stephen Hawking there'd be queues of Republicans (and Daniel Hannan) round the block at Fox News just to say "there you go, Ted Kennedy is dead because of the NHS".
My main knowledge of Ted Kennedy is somewhat out of date, really: in a lot of Hunter S Thompson's 1970s work (particularly the superb Fear and Loathing: On the Campaign Trail '72) he's portrayed as a president-in-waiting, just waiting for the right year to make his move.
Of course, that year never came. 1980 was the closest he got, but he was trying to take on a Democratic incumbent - Jimmy Carter - and trying to unseat an incumbent 'from within' is extremely hard. Perhaps if Carter had lost to Ford in 1976, things would have been very different in '80 and Kennedy would have made it to the White House, and we'd never have had 'Reaganomics' and therefore avoided the collapse of the economy in 2008; it's a fascinating thought.
The Kennedy dynasty is looking somewhat depleted in the US these days; I'd suggest drafting in violinist Nigel Kennedy to make up the numbers a bit. But God forbid, not Radio 2's Sarah Kennedy - that's all the Americans need. Stick with Rush Limbaugh - he has a tiny brain, but at least it's somewhere in there.
Dunno what happens in the US Senate now: do they have a by-election in Massachusets? I have no clue.
